ELECTRIC SWITCH.

Specification of Letters Patent.

Patented Nov. 30.1915.

. it'rmzg concern:

it known that 1', Autumn J. TIzLr-r, a citizen of the. United States, and n resident of the city of New Yorlczborough of 5 Broolrlyn. in the county of Kings-and State of New York, have invented a new and Ln proved Electric Switch, 0')"- Which the following is a full, clear, and exact description.

My invention has for its object to provide an electric switch particularly well adapted for use on candelabra in which a switch member is mounted to rotate on a central tube through which the wires lead one of the wires being connected withv the switch member for making and breaking the circuit.

.Anothcr object of the invention is to dispose the switch member in a. collar with which it is connected by a ratchet so that while theswitch will be operated by rotating .-the collar in one direction the collar may be rotated in the opposite direction relatively to the switch member.

Additional objects of the invention will amzeu-r in the following specification in which the preferred form of my invention is disclosed.

In the drzrwings similar reference charar so ters refer to similar parts in all the. views in which- Figure 1. a sectional elevation showing my invention; Fig. 2 is another elevation partially in section showing other features oi? the invention; Fig. is n. sectional frag nentary View showing the switch members; Fig. i 'sn. LlOiullR'leW on the line H i= 1; Fig. a sectional View on the i of Fig. 1; and Fig. I is n perspectire view showing the rotary switch member.

By referring to the drawings it will be soon that a tube i) is provided, wires '11 and being: disposed in the said tube 10 and painghut of the said tnhe 1.0 through the iii. The wire 1 is then connected the binding post 14., the wire 12 extendin through the phig' l-fi and being conwith the spring Contact member 16 rnuntcrlmi the insulating switch member A l" "lilting material with which the ictcd insulating the conthe cmilrlCt point 18. constructed in the ii I il'ifr-ii; llia'i I h iii-Farm: two teeth of the. ratchet and the other two teeth being formed zit l9 mid 20. lhe switch member 17 is preventhas two resilient extending contact arms 23 which are corincctml together lcctricnlly so that when the contact :irms'Q l engage the contact points I and IR. a circuit will be completed from the wire 12 to the CODERCC point 16 to one of the contact arms 23 to the other contnc'r arms 23, l Contact point 18 with which the wire 21 is connected, thence to the wire. lending to a binding post which is a companion to the binding post 14, the said binding post l innd being, connected with the lamp.

Disposed around the rotary switch member there a collar 28 having a head 27 with which an end of the s iring 28 engages, this spring also e iring the rotary switch member furl. "ng the rotary switch member 532 with its contact arms 23 yieldingly in engagement with the contact points 15 and 18 or with the switch member 17 at its ratchet teeth 19 and 20. The collar 26 has inner tooth $39 best illustrated in Fig. 53 of the drnwin s. with which a ratchet 3O gcs, this ratchet 3O iieing provided in n recess '31 in the. rotary switch member 22 and being held yieldingly extended by a "inn-G 2. With this construction, the. rotary switch member may be rotated by the. colic r L' l. when the Stilt'l collar 26 rotates in one direction it being possible for the collar to be rotated in the opposite direction and relatively to the rotary switch member .22. This constrm-tion makes it possible to reverse the movement of the collar 26 without damaging the switch.

The collar 28 is hold inplnceon the tulle i by :1 nut 33 whicn meshes with a thread 34 on the. tube 10, this nut having a flange 35 against which a or il 'inny hc disposed, the cup 31'' having an opening through which n hollow stem hair 1;; :in outer thread is disposed, a tuhg having on inner t d 40 hing with the thread. for 11;: the clip ill; ilfjfllfli i the llzxllgHQdz}.

' H and 3 rm: connected in tin customary my invention l thence to the claim as new and desire to secure by Letters Patent:

1. In an electric switch, a central tube, a switch member mounted on the tube and having two contact points insulated from each other, two wires in the central tube,

one of the wires leading to a contact point, a wire leading from the other contactpoint for cooperating with the other of the first two wires, a rotary switch mounted on the central tube for connecting the contact points, there being a recess in the side of the rotaryswitch, a pawl in the recess, a spring for pressing the pawl yieldingly away from the recess'and a collar disposed around the rotary switch member and having inner teeth for engagement by the pawl 2. In an electric switch, a central tube, a switch member secured around the tube and provided with two contact pbints, the switch member having an outer annular seat, a second switch rotatably mounted on the central tube for cooperating with thefirst switch member, a collar disposed around the second switch member and having means for operating the latter, the collar being disposed beyond the annular seat to embrace an arti ficial candle tube seated in the seat, and means for 'yieldingly pressing the second switch member against the first switch member.

In testimony whereof I have signed my name to this specification in the presence of the two subscribing witnesses.

ARTHUR JAMES TIZLEY.
